For dynamic arrays and associative arrays, something like this would work:
template ArrayElementType(T : T[])
{
alias T ArrayElementType;
}
template AATypes(T)
{
// todo: static assert if T is no AA type here
alias ArrayElementType!(typeof(T.keys)) key;
alias ArrayElementType!(typeof(T.values)) value;
}
Thinking about it, it's probably simpler to just use
typeof(array[0])
typeof(aa.keys[0]), typeof(aa.values[0]).
Cheers,
Christian
